Abstract
A process and device for machining bars, tubes or tube blanks, especially strand-cast copper blanks, in which the work piece to be machined-supported in the cross-plane of the metal-cutting device is cut on its periphery and along its length, while the die and the work piece are continually moved relative to one another in the longitudinal direction of the work piece. At least one die rotates concentrically around the work piece, which is held in a rotation-proof manner, on a plane inclined toward the longitudinal axis of the work piece and with its cutters simultaneously machines two areas of the work piece surface that are located opposite to one another.
Description
The present invention relates to bar, pipe or pipe, especially Lian Xuzhuzao copper pipe base, carry out the method and apparatus of machining, in this method and apparatus, processed work mounting s excircle of workpiece on week in the transverse plane of machining, and at cutter and workpiece along workpiece vertically during continuous motion relative to one another, along its excircle of Workpiece length milling.
As everyone knows,, adopt the ingot casting or the hollow ingot of continuous pouring or cross roll pierced billet usually as the roughing material of bar or pipe, before they are done further processing, must elder generation's its outer surface of processing.If for example the hollow ingot (pipe) of copper is sent into cold rolling or cold drawn equipment, then must remove the oxide skin on the hollow ingot outer surface, otherwise this oxide skin can be pressed in the product and goes, thereby significantly reduce end product quality.
At present, hollow ingot is leveled through pickling, scraping, milling or plane before further being processed into pipe, all will remove many materials from the surface more or less in all cases.The reduction minimum on surface during pickling, what certainly stay after the pickling is still a coarse surface, when further processing for example scraping, at first must preform.So the wall thickness of hollow ingot is thinner.Proved already that the appropriate method on processing bar, pipe or pipe surface was surperficial milling, this milling is known as the single-point cutter of rotary milling tools usually, or vertical milling cutter of a plurality of milling cutters is arranged.When adopting single-point cutter, milling cutter rotates around the workpiece of wanting milling in a vertical plane prejudicially, and the vertical milling cutter of conduct is to adopt profile milling cutter, and the profile of its shape and workpiece matches, longitudinally process outer surface, need around workpiece, be provided with a plurality of milling cutters side by side usually.
In these two kinds of method for milling, supporting reliably under the cross force effect that all must be produced when the milling by the workpiece of milling, especially under long circular cross section situation, Jiao Zhu copper pipe base for example, this cross force can make this copper pipe base bending, thereby can cause worsening the error of wall thickness once more.
The shortcoming of these two kinds of method for milling is slow; In the process of single-point cutter, strengthen feed and in a plane, can not accomplish.For vertical milling cutter, although can be with big feed, yet suffer a loss in time, because must process several times at different circumferential sections along the length of workpiece.If process with a plurality of milling cutters along circumference, then should improve power, this must significantly improve the cost of machine and cutter.Especially under the very long situation of workpiece, on the longitudinal axis of workpiece, can cause very big power.
The objective of the invention is, to long circular cross section workpiece, for example Jiao Zhu the copper pipe base that contains tolerance is processed its outer surface with high feeding speed and favorable surface quality, wherein, should adopt automatable equipment.Even also should be able to milling under indeformable situation for unsettled farm labourer's part.
The method of being advised is characterized by in order to achieve the above object, at least one cutter one with workpiece longitudinal axis plane inclined in one heart around the rotation of this workpiece, and with the cutting edge of cutter surperficial two zones that are in relative position of machining workpieces simultaneously.The present invention thereby comprise, with a cutter simultaneously on workpiece two the circumference area of arranging are carried out Milling Process, at this moment, cancel each other at the cutting force that opposite side produces transverse to workpiece.
Bring outstanding advantage by another feature of the present invention, by this characteristics specify, establish two cutters that be close to and that rotate around workpiece with one heart in two Different Plane, these two planes are in 90 ° of directions and the public workpiece longitudinal axis tilted configuration of staggering mutually.
Only just can be by the whole excircle of suggestion machining workpieces of the present invention with two cutters, wherein, by tool plane slightly being tilted and by 90 ° of incline directions that stagger, forming a polygon cross section, it is made up of 4 sections always paired opposed elliptic arcs.These two cutters can only be used once the just whole length of processing work with very high feeding speed, and four circumference area on border each other on the processing work simultaneously.
If by the characteristics specify on another method of the present invention, cutter rotates around axis of workpiece in opposite direction, no matter be the bite that acts on along circumferentially then, still, all offset automatically transverse to the power of workpiece effect.Vertically the remaining cutter power of sending is very little along workpiece.
For implementing the equipment of the method, it is characterized by, Tool Design is interior milling cutter, the internal diameter between the Tool in Cutting sword is slightly larger than the external diameter of the workpiece of wanting milling.
When the internal diameter between the Tool in Cutting sword only is slightly larger than the workpiece external diameter of wanting milling, just obtain above-mentioned polygon shape of cross section with cutter is tilting, cutter is more little with respect to the gradient of workpiece longitudinal axis, and then this polygon shape of cross section is similar to circular cross section more.
But at the internal diameter timing of cutter, the gradient of best fixed cutting tool.In this way, change the external diameter of being processed by the bite of adjusting interior milling cutter, thereby can obtain stable machine construction.Accurately adjust cutter with respect to workpiece longitudinal axis position, and when accurately adjusting milling cutter diameter on the cutterhead, can obtain high-precision wall thickness.
In order to guarantee machining accuracy, by another characteristics specify of the present invention, be placed on the workpiece on the deflector roll, do non-rotatable fixing in the end of cutter both sides, and can fix by means of clamping and fixed bar vertically.Wherein can notice, the as close as possible cutter of guiding device, and two cutters also should rotate as far as possible contiguously.Clamping and fixed bar are also born the effect of workpiece guiding device of first being processed in machine simultaneously.
By another feature of the present invention regulation, pack into arrival end in the cutter of workpiece is designed to the guiding sleeve of workpiece at least, it can be adjusted into gapless guiding device automatically, guide workpiece with one heart.This guiding sleeve guarantees precision centering ground pack into bar, pipe or pipe, and thereby helps to control the tolerance of necessity.Following design can think to have within the scope of the invention same meaning,, forms the milling cutter assembly by the guiding device of cutter and instrument that is, can longitudinally move with respect to workpiece, and its effect moves with respect to cutter as workpiece.
The invention has the advantages that, only just can under the situation of machine construction compactness, obtain to have improved feed compared with prior art unusually with two milling cutters.Between deflector roll,, the processing of tolerance be can contain, therefore, all in all, a kind of compactness, the stable and low scheme of cost proposed surface of the work than short bearing length and this process of exerting all one's strength and offsetting.
Accompanying drawing has been represented embodiments of the invention, and is illustrated below.Wherein:
Fig. 1 implements the milling device side view by the inventive method;
The amplification of Fig. 2 milling cutter is represented; And
Clamping that Fig. 3 fixation workpiece is used and fixed bar.
Accompanying drawing reduced representation by equipment of the present invention, be used for understanding basic principle.Represent to be contained in milling machine on the basis 2 with numeral 1 among Fig. 1, between two side arms 3 of milling machine are with 4 the workpiece 5 that will process is housed, workpiece 5 is clamped and is fixed between two clampings and fixed bar 6 and 7, and the back also will describe in detail them.Workpiece 5 is as clamping and fixed bar 6 and 7 is placed on that deflector roll can prevent between pinching end crooked on the deflector roll 33.
Process with cutter 8 and 9 pairs of workpiece 5, cutter 8 and 9 is contained on the knife rest slide carriage 10, and knife rest slide carriage 10 itself can vertically be contained on the guide rail 11 continuously movably along workpiece.Cutter 8 and 9 is installed obliquely by mode of the present invention, and does not upward have the drive unit 12 of expression in detail to drive rotation by figure.
Fig. 2 has described the vertical view of cutter 8,9 equally in the mode of simple signal, as seen from the figure, these two cutters tilt with respect to pipe longitudinal axis 13, and both all have inclination angle γ, by cutter 8 visible these oblique angles that are illustrated in left.The gradient of cutter 9 has identical oblique angle, and it is concentric and perpendicular to the figure paper plane with pipe longitudinal axis 13.The cutter 8,9 that is bearing on bearing 14 and 15 all is designed to interior milling cutter, and is provided with the blade 16 that distributes along inner periphery, comes the periphery of milling workpiece 5 with these blades 16.The oblique angle γ of the internal diameter between the blade 16 and cutter 8 and 9 should elect as, and at cutter 8,9 during around workpiece 5 rotation, their blade 16 is the opposed district on the machining workpieces always.Therefore, the cutter inclined plane of these two cutters 90 ° of directions of being arranged to stagger mutually.When as regulation like that, the internal diameter between the blade only is slightly larger than the external diameter of workpiece 5, and oblique angle γ selects hour, and the cross section of the workpiece 5 that then obtains slightly is polygon, the transition of easing up between 4 polygon sides.Like this a kind of slightly is polygonal milling shape of cross section and is suitable for doing further processing, that is to say, the cross section of workpiece 5 is not that this circular fact is harmless after the milling.
Foregoing, cutter 8 and 9 switched in opposite, so, try hard to make the power of instrument rotation to cancel each other out.Therefore the guiding of instrument and fixing fairly simple.The driving of cutter by among the figure not the drive unit of expression carry out by means of gear 17,18, they mesh with roller gear 19,20 on the cutter 8,9; Bearing 14 and 15 is bearing on knife rest 21 and 22, and knife rest 21 is connected with knife rest slide carriage 10 with 22.
For can be under the minimum situation of scrap rate the surface of processing work 5 accurately, require workpiece is fixed on exactly the center of rotary cutter 8,9.For this purpose, establish guiding sleeve 24 at the arrival end of equipment, guiding sleeve 24 is pasting surface of the work by 8 and is forming along the segmental arc of workpiece circle distribution.In the front portion of sleeve 24 (right part), on the excircle of sleeve, make the conical surface, this conical surface made corresponding conical surface on knife rest 21 abuts in.By means of there not being the in detail piston/cylinder component 25 of expression on the figure, make sleeve along the vertically moving of workpiece 5, the segmental arc that can make sleeve 24 is towards moving with digital 26 conical surfaces of representing, and thereby is pressed on the surface of workpiece.Workpiece can accurately be felt relieved and be guided in this way, and wherein, clamping force should be elected cutter or knife rest slide carriage 10 as can do feed motion with respect to workpiece 5 surfaces.
The port of export by present device is provided with material roller 27, and their guidings clamp and fixed bar 7 and/or workpiece 5, and when process begins and finish, draw in and discharge workpiece.The supported box of material roller 27 is provided with discharger 28, and it is used for preventing that smear metal from entering between the surface and material roller 27 of workpiece 5, and is pressed into there in the softer material and goes.
Fig. 3 schematically illustrates the operation principle of clamping and fixed bar.Workpiece 5 inserts and clamps and fixed bar 6 (Fig. 1 left side), and by means of tension section 28, is stretched on workpiece 5 inner peripherys by the conical surface 29 and 30, and the conical surface 29 and 30 usefulness pull bars 31 are handled.Therefore, workpiece 5 can along circumferentially non-rotatably be fixed on clamp and fixed bar 6 on, and can be pressed on the end face of workpiece 5 by middleware 32 vertically, clamping and fixture need not be acted on the excircle of workpiece 5.So the processing to workpiece 5 can proceed to its end always.
Other end effect at workpiece 5 has clamping and fixed bar 7, and its part in Fig. 3 is illustrated in the bottom of figure.Between clamping and fixed bar 6 and 7, fixedly mounting workpiece, and knife rest slide carriage 10 is being with cutter 8,9 to move continuously along the workpiece total length.When the knife rest slide carriage was sent to, relevant deflector roll 33 was outwards swung, and puts back again after cutter passes through, to obtain supporting as far as possible reliably.
The present invention has only just made a kind of equipment of compactness with two milling cutters 8,9, it has short length of support along Workpiece length between deflector roll 33.By act on the workpiece 5 feeding power as can be seen, the method is exerted all one's strength and is cancelled each other because Xuan Zhuan cutter 8,9 in opposite direction, their moment of torsion is cancelled each other.Because drive unit is simplified and the degree of accuracy of method for milling improves, so tolerance is minimum.Simultaneously at 4 circumferential sections respect to one another with two workpiece processing tools 5, improved the efficient of milling process, so can in the shortest time, only walk a process, just finish the processing of whole outer surface along the length of workpiece 5.In order to control scrap rate to workpiece 5 external peripheral surfaces, can adjust cutter 8,9 and/or blade 16, can consider to adopt the adjusting device of automation this moment.By making cutter 8,9 reverse rotations, can save the device of preventing the workpiece rotation basically, only begin in process, when having only a cutter 8 or 9 to enter work, just must overcome the effect of moment of torsion the short time.For this reason, clamping and fixed bar 6,7 can play this effect, and they obtain these effects by sleeve 24.Sleeve 24 is used for accurately guiding workpiece in cutter 8,9 locations, and very advantageously be that sleeve 24 arrives near the cutting face of cutter always this moment.The established angle that cutter 8,9 is very little with respect to axis of workpiece can not cause significant bending force on workpiece, particularly because processing carry out at two opposite sides of workpiece simultaneously.Born only be act on workpiece central authorities send cutter power, having under the situation of enough rigidity, this power can easily be transmitted.
